How to Use Grammarly for Better Writing

Writing clearly and correctly matters more now than ever — in professional emails, client documents, Slack messages, LinkedIn posts, and job applications. Grammarly catches what spell-checkers miss: it understands context, tone, clarity, and engagement, and can tell the difference between a grammar error and a sentence that’s technically correct but needlessly complex. You’ll find the complete rundown in our Complete Guide to Software and Apps.

This guide covers the complete Grammarly toolkit — free features that deliver real value, Premium features that justify the subscription, and the specific workflows that make the most of the tool across different types of writing.

Installation and core workflow

The browser extension is the most versatile starting point — it runs automatically in almost every web-based text input: Gmail, Google Docs, Outlook Web, WordPress, LinkedIn, Twitter/X, Slack, Notion, HubSpot, and thousands of others. Install from grammarly.com → create a free account → the green G button appears in every text field you click. Suggestions appear as underlined text — click any underline to see the suggestion and accept or dismiss it.

The Grammarly Editor (editor.grammarly.com or the desktop app) is the full writing environment for documents and longer content. Paste text or write directly, and the right sidebar displays all suggestions organised into categories:

• Correctness: grammar, spelling, punctuation — errors, not stylistic preferences
• Clarity: concise phrasing, sentence structure — technically correct but harder to read than needed
• Engagement: varied vocabulary, dynamic word choice
• Delivery: tone, formality, appropriateness for the audience

Effective suggestion workflow: start with Correctness first — these are actual errors, and fixing them before addressing style gives a cleaner base. Then Clarity and Engagement. Finally Delivery to check tone matches the intended audience. Don’t accept all suggestions uncritically — each one deserves evaluation in context, because Grammarly’s suggestions are sometimes wrong about writer intent or inappropriate for the specific register of the document.

Keyboard shortcuts make the review loop significantly faster: Tab cycles through suggestions; Enter accepts the current one; Escape dismisses it. Working through a 1,000-word document’s suggestions using only the keyboard takes under 10 minutes. Clicking each suggestion individually takes considerably longer and most users stop partway through as a result.

Free vs Premium — what you actually get

The free plan catches the errors that damage credibility: misspellings, subject-verb agreement errors, missing commas in compound sentences, incorrect apostrophe use, and commonly confused words (their/there/they’re, affect/effect, lay/lie). If your writing is already technically correct and you want to improve its readability, conciseness, and impact, the Premium plan’s clarity and engagement suggestions are where the real improvement comes from.

Premium’s clarity suggestions are what most differentiate it from a spell-checker. They identify sentences that are technically correct but harder to read than necessary:

• Redundant phrases (“due to the fact that” → “because”)
• Passive voice that should be active
• Nominalisations — using a noun where a verb would be clearer (“make a decision” → “decide”)
• Hedge words that weaken the point (“it could be argued that” → just state the argument)

In everyday writing these patterns accumulate invisibly. A document reviewed with Grammarly Premium’s clarity suggestions typically becomes 10–20% shorter and significantly easier to read. For most writers, this is a larger improvement than fixing the grammar errors the free tier catches.

The Plagiarism Checker (Premium) compares text against over 16 billion web pages and academic papers, flagging passages that match published sources with a similarity percentage and source link. Useful for academic work and content marketing — run any long-form piece through it before publishing to catch unintentionally close paraphrasing that could raise academic integrity concerns or create duplicate content issues for SEO.

Grammarly Go — AI rewriting

Grammarly Go is the AI-powered generation and rewriting feature integrated directly into the editor and browser extension. Unlike suggestion-based corrections that modify existing text, Go generates new content or rewrites existing content based on a prompt. In the editor: click the wand icon → choose from options like “Make it shorter,” “Make it more formal,” “Improve the tone,” “Improve clarity,” or “Write a reply to this email.”

The most effective approach: compose a rough draft of what you need to say without worrying about polish — a complaint to a vendor, a request for a deadline extension, a cold outreach message. Then highlight the draft and use Grammarly Go to improve tone, make it shorter, or change the formality level. Draft-then-polish is more efficient than trying to write perfectly on the first pass, especially for high-stakes communications where tone matters.

The inline rewriting in the browser extension makes Go accessible in context — inside Gmail, Outlook, or any web-based text field, the G button has an “Improve it” option that applies Go suggestions to selected text without leaving the application. Tone adjustment is particularly useful: writing a firm but professional response to a difficult client, selecting the draft, and asking Go to “make this more diplomatic while keeping the core message” refines the language in seconds.

Document Goals — the feature most users never set

Before editing any document in the editor: click “Set Goals” → choose the intended Audience (General, Knowledgeable, Expert), Formality (Informal, Neutral, Formal), Domain (Academic, Business, Email, Casual, Creative), and Tone (Informative, Descriptive, Convincing, Narrative). These settings shift which suggestions Grammarly prioritises.

A formal business document gets stricter passive voice suggestions than casual social media copy. An academic paper gets stricter complexity suggestions than a blog post. Setting goals accurately makes the suggestions more relevant to the actual context — without this, Grammarly applies generic defaults that may not fit the specific piece.

Team Style Guides — the Business plan’s biggest value

For organisations with multiple writers producing content under one brand voice, Team Style Guides are where the Business plan earns its cost. Administrators define rules: preferred spellings (“e-commerce” or “ecommerce”?), banned words or phrases (never use “synergy” or “leverage” as a verb), required capitalisation (“Always capitalise the company name”), and tone guidance. Every team member’s Grammarly flags style guide violations in real time — creating consistent brand voice without requiring a human editor to catch every deviation across blog posts, sales emails, social media, and support responses.

Microsoft Office and mobile integrations

The Office add-in (install from grammarly.com) adds a Grammarly panel in Word and Outlook sidebars — suggestions categorised identically to the editor, accepted with one click. In Word, it provides the full Premium treatment including plagiarism check and clarity suggestions for long documents before they go for review. In Outlook, it catches grammar errors in client emails that Outlook’s native spell-checker would miss.

The mobile keyboard (iOS and Android) extends Grammarly to every text input on the phone — messaging apps, social media, mobile email. Set it as the default keyboard in the phone’s settings. The keyboard catches the autocorrect substitutions and typos that mobile keyboards introduce — particularly valuable for client-facing messages written on the go, where the informal context of phone typing can produce less professional text than intended. The tone detector in supported apps flags when a message sounds unintentionally harsh before it’s sent.

Personal Dictionary and customisation

Account → Customisation → Personal dictionary → add words. Add every brand name, product name, industry-specific jargon term, or field-specific acronym used in your work. Once added, these words are never flagged again across any text edited through Grammarly. For technical writers, developers, and subject-matter experts, this is the setup step that makes Grammarly usable without constant interruptions from correctly-spelled technical terms being flagged as errors — it lets actual writing quality issues be more visible.

Using Grammarly to actually improve your writing

Instead of accepting every suggestion automatically, read the explanation before deciding. Grammarly explains its suggestions with a brief rationale — “This sentence is passive; consider restructuring for more direct writing” or “This phrase is redundant; ‘future plans’ can be shortened to ‘plans.’” Reading these explanations builds understanding of the underlying rule, which reduces how often the same error appears in future writing.

Grammarly as a writing tutor rather than a writing crutch means engaging with the feedback actively — the goal is fewer suggestions needed over time as writing improves, not the same volume of suggestions in every document forever. Tracking whether the suggestion count per 1,000 words decreases over a month of regular use is a simple metric for measuring genuine writing improvement. Our guide on using ChatGPT covers the complementary AI writing tool for longer-form generation and more open-ended writing tasks where Grammarly’s correction-focused approach isn’t the right fit.

Real-world workflows — where Grammarly fits in practice

Client-facing email workflow: write the email in Gmail or Outlook Web → Grammarly’s browser extension automatically checks it → red underlines flag errors, yellow/blue underlines flag style suggestions → review suggestions, accept relevant ones → send with confidence. Takes an extra 30–60 seconds and prevents the kind of embarrassing typos or inappropriate tone that can affect professional relationships.

Long document workflow: draft the document in Google Docs or Microsoft Word → paste into the Grammarly Editor (or use the Office add-in in Word) → set Document Goals for the intended audience and formality → work through Correctness suggestions first, then Clarity → use the plagiarism checker before submitting → return the polished document to the native application. For academic papers, professional reports, and proposals, this two-stage process (draft in familiar environment, review in Grammarly Editor) is more thorough than the browser extension alone.

Social media and short-form content: write in the native platform (LinkedIn, Twitter/X) — Grammarly’s browser extension checks in real-time in these text fields. The tone detector is particularly useful here because social media tone misjudgments (posting something that reads as confrontational when you intended it to be assertive) are highly visible and hard to retract. For LinkedIn in particular, checking that professional posts hit the right tone before posting prevents the common mistake of publishing something that sounds harsher than intended.

Shared team content (Business): set up the Team Style Guide with brand-specific vocabulary rules → all team members’ Grammarly flags violations automatically → editors spend time on structural improvements rather than catching basic style inconsistencies. This workflow is most valuable for content marketing teams producing high volumes of blog posts, for sales teams writing many individual outreach emails, and for customer support teams whose written responses reflect the brand.

Grammarly works best when it’s always on — the browser extension running in the background, the mobile keyboard set as default. The value accumulates across thousands of small writing moments (emails, messages, comments) rather than just in the big writing projects where you remember to check carefully. Getting into the habit of having it active everywhere is the difference between catching 20% of your writing and catching 90% of it. You might also run into How to Use Google Docs.
